Hi all, I have a rather large (almost 120,000 lines) xml file, processing pulls in another large xml file. The project compiles under mkiv; with lmtx, I get tex error > tex error on line 8 in file : TeX capacity exceeded, sorry [reference count=32767] <macro> \reallanguagetag just twenty pages shy of the end of the document. There is an error log with this content: return { ["errortype"]=3, ["filename"]="", ["lastcontext"]="\n\n\n<macro> \\reallanguagetag \n \n<macro> \\reallanguagetag #1->\\ifcsname \\??languagelinked #1\n \\endcsname \\lastnamedcs \\else #1\\fi \n<macro> \\setusedlanguage #1->\\edef \\currentusedlanguage {\\reallanguagetag {#1}\n }\\ifempty \\currentusedlanguage \\let \\currentusedlanguage \\currentlanguage \\always\\let \\usedlanguageparameter \\languageparameter \\orelse \\ifx \\currentusedlanguage \\v!global \\let \\currentusedlanguage\n\n<macro> \\typo_delimited_push ...\\currentdelimitedtext {#1}\\edef \\m_delimited_argument {#2}\\ifempty \\m_delimited_argument \\typo_delimited_set_language_nop \n \\else \\typo_delimited_set_language_yes \\fi \\let \\currentparentdelimitedtext \\currentdelimitedtext \\global \\advance \\c_typo...\n\n<macro> \\delimitedtext [#1]#*[#2]->\\dontleavehmode \\typo_delimited_push {#1}{#2}\n \\edef \\p_delimited_method {\\delimitedtextparameter \\c!method }\\ifx \\p_delimited_method \\v!font \\expandafter \\typo_delimited_fontdriven \\else \\expandafter \\typo_delimited_other \\fi \n\n<to be read again> \n {\n...\n\n<initial> \n ", ["lastluaerror"]="", ["lasttexerror"]="TeX capacity exceeded, sorry [reference count=32767]", ["lasttexhelp"]="If you really absolutely need more capacity, you can ask a wizard to enlarge me.", ["linenumber"]=8, ["offset"]=10, ["skiplinenumber"]=8, } In mkiv, these are the stats at the end of the run: mkiv lua stats > used config file: selfautoparent:/texmf/web2c/texmfcnf.lua mkiv lua stats > used cache path: /mnt/shared/lmtx/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e mkiv lua stats > resource resolver: loadtime 0.009 seconds, 1 scans with scantime 0.005 seconds, 0 shared scans, 27 found files, scanned paths: /home/tas/texmf mkiv lua stats > stored bytecode data: 455 modules (0.122 sec), 96 tables (0.007 sec), 551 chunks (0.130 sec) mkiv lua stats > traced context: maxstack: 1422, freed: 2, unreachable: 1420 mkiv lua stats > cleaned up reserved nodes: 63 nodes, 9 lists of 442 mkiv lua stats > node memory usage: 17 attribute, 4 attribute_list, 1 glue, 51 glue_spec, 3 kern, 2 penalty, 2 temp, 2 user_defined mkiv lua stats > node list callback tasks: 8 unique task lists, 9336 instances (re)created, 177413 calls mkiv lua stats > h-node processing time: 4.800 seconds including kernel mkiv lua stats > attribute processing time: 0.617 seconds front- and backend mkiv lua stats > driver time: 0.886 seconds mkiv lua stats > used backend: pdf (backend for directly generating pdf output) mkiv lua stats > jobdata time: 0.161 seconds saving, 0.052 seconds loading mkiv lua stats > callbacks: internal: 261417, file: 319, direct: 3, late: 31831, function 200128, total: 493698 (464 per page) mkiv lua stats > randomizer: resumed with value 0.47143577262518 mkiv lua stats > positions: 9535 collected, 9535 regular, 0 special mkiv lua stats > v-node processing time: 0.401 seconds mkiv lua stats > result saved in file: plutarchusvitae.pdf, compresslevel 3, objectcompresslevel 1 mkiv lua stats > loaded patterns: de::3 en::1 la::65, load time: 0.000 mkiv lua stats > xml load time: 0.648 seconds, 4 files, 4 converted mkiv lua stats > lxml preparation time: 0.626 seconds, 233814 nodes, 578788 lpath calls, 578743 cached calls mkiv lua stats > interactive elements: 0 references, 37 destinations mkiv lua stats > margin data: 10798 entries, 0 pending mkiv lua stats > loaded fonts: 9 files: garamondpremrpro.otf, sabonltstd-bold.otf, sabonltstd-italic.otf, sabonltstd-roman.otf, kadmosu.otf, oldstandard-bold.otf, oldstandard-italic.otf, xitsmath-regular.otf, dejavusansmono.ttf mkiv lua stats > font engine: otf 3.113, afm 1.513, tfm 1.000, 17 instances, 6 shared in backend, 0 common vectors, 6 common hashes, load time 0.146 seconds mkiv lua stats > used platform: linux-64, type: unix, binary subtree: texmf-linux-64 mkiv lua stats > used engine: luatex version: 1.13, functionality level: 7420, banner: this is luatex, version 1.13.0 (tex live 2021) mkiv lua stats > used hash slots: 47131 of 65536 + 250000 mkiv lua stats > lua properties: engine: lua 5.3, used memory: 601 MB, ctx: 579 MB, max: unknown MB, hash chars: min(64,40), symbol mask: utf (τεχ) mkiv lua stats > runtime: 22.310 seconds, 1068 processed pages, 1068 shipped pages, 47.871 pages/second system | total runtime: 213.928 seconds Is texmfcnf.lua still the configuration file I need to look at for this kind of problem?
