Hi, I'm reprting another problem with jammed context/luatex. To avoid my previous problem with table I tried trunk version of luatex. One problem is solved, another one appeared - but now it's not so easy to determine what causes the trouble. I found following: When I try to compile my thesis(quite long doc.), everythig seem to work fine until final step(final pdf file has 99.8% of its normal size) where it hangs using 100% CPU, just after this report: report:lua : loaded patterns - cz:cz:pat:exc:3 en:en:pat:exc:2 lua : current memory usage - 294785281 bytes lua : cleaned up reserved nodes - 18 nodes, 11 lists (of 100) remark : temporary fallback to base mode for tlig and trep ) (see the transcript file for additional information) node memory in use: -3138 words out of 100000 I uncovered that when I comment out line with my font settings (\usetypescriptfile.................) leaving everything default, complilation passes OK. It's strange, because another thin that helps is deleting some lines of the source file, i.e. this line: \part{something} Deleting of some other different lines helps too, I can't find the rule, sorry. I'm still not able to make simple document causing the same problem. I'm sorry for bothering you again. ZS
