Hello. This is a bit of a long shot. I've done a bit of Google-search, but that only gives a small number of hits, most of which are unanswered questions on mailing lists or message boards. Our web server occasionally gives the following 'errors' in the error_log file: [Mon Apr 23 12:41:40 2007] [info] [client 12.34.56.78] send mmap timed out and, more frequently: [Mon Apr 23 12:41:40 2007] [info] [client 12.34.56.78] (32)Broken pipe: client stopped connection before send mmap completed This usually isn't a problem and it never worried me (it is, after all, marked as "info"), until a number of the former errors, followed by a number of the latter errors (about 30 of each) caused the server to crash. The errors were all related to the same IP address and, as far as I can see, this belongs to a genuine user. I did, however, find in the access log files that their results returned httpd status '206' (partial content) and the number of bytes on large files, was always a nice rounded number, like 32768 (which is 2^15). It suggests that the problem has to do with the user downloading only parts of larger files (pdfs/gifs) and, I would guess, leaving an httpd process waiting for it to finish? At least the number of httpd processes had reached its maximum (which is why the server crashed). But I don't know if my guesses are correct. And even if they are, what has really happened (for instance: is this really a problem with the client or with the server). And, of course, how to make sure this won't happen again.
