Note, before 2.4, a single thread can execute Lua scripts at once, with the others waiting behind, and if the Lua load is important, maybe this can happen (but I've never experienced it yet, and the premption interval is short enough not to cause issues in theory). However the trace shows an issue on setjmp(), which doesn't make much sense in theory, unless we consider that it's triggered there because it's the first syscall after waiting too long. Maciej, if this happens often, would you be interested in running one machine on 2.4-dev11 ? We'd need to have a quick look at your config (off-list if needed) to figure what Lua parts could run in multi-thread. Cheers, Willy
