Hi there,
i wrote several times to the list asking for help with a problem regarding process limits on linux, but never got an answer. today i found this story: http://www.mysql.com/press/user_stories/handy.de.html here are the relevant sentences: "We had some process limit problems on our Linux Systems, but thanks to your support we where able to patch the linux boxes and move the limit to a size that meets our needs (we've got an average of about 1600 concurrent threads per server)." These people use 2.2 Kernels so i dont know if the mentioned kernel and glibc patching is also relevant for me, as i am using 2.4 kernels only. Here is my problem in detail: i am using mysql-3.23.55 binary packages on linux 2.4.20 and i raised ulimit values and configuration in my.conf to allow more then 1500 threads. but when there are around 750 threads a new client connecting is told something like that (dont have the errno at the moment, i think its 11): "cant create new thread, perhaps you are out of memory or there is a os-depended bug". The machine only runs apache and mysql and is a Xeon 2x2 2.4 Gz with 2 GB of RAM. cat /proc/meminfo sais that more then 1 Gig is used for caching, so memory should be no problem . Please, if you have any ideas, let me know. If it is a kernel issue, tell me to go to linux mailing lists or if its some kind of "secret issue" only the support will be able to answer let me know that.
