It looks like comments on my blog are now broken but I can't find why. The ruby code is fh.flock( File::LOCK_EX ) and ruby process loops on the following 3 lines when you try to post a comment and then I need to kill the ruby process or all the blog gets broken:
--- SIGVTALRM (Virtual timer expired) @ 0 (0) --- sigreturn() = ? (mask now ) flock(4, LOCK_EX) = ? ERESTARTSYS (To be restarted)
For some reason, the lock works fine when I post a new entry to the blog while it tries to lock the same file...
The code did not change and the server software versions did not change much so I really don't have any clue :(
