HttpTransport X server socket accept failure: Too many open files
|
|
|
| Hello,
Has anyone received the following error?
HttpTransport X server socket accept failure: Too many open files
This was logged repeatedly until the machine was rebooted. During the
time that this error was being logged we had intermittent connection
problems. This problem was visible to the end user as a 500 internal
server error which was displayed by IBM HTTP Server.
We are running WebSphere Commerce Professional 5.4 on a Red Hat Linux
7.2 server. The version of WebSphere Application Server is 4.0.7. I
was able to connect to place an order during the time when these these
messages were being logged. Other people were unable to use the site
and received the 500 error page.
I searched for this error message on the WCS and WAS newsgroups. I
attempted to increase the file handle limit using ulimit -n 4048. I
did this while the machine was still experiencing the problem and it
did not fix it.
I would appreciate any thoughts on what might be causing this problem
and any possible solutions. It has only happened once in 9 months of
operation but I would prefer that it did not happen again.
I am posting this to both the WCS and WAS groups so I hope that is not
a violation of netiquette. If it is please let me know.
Thanks,
John

Talk to your sysadmin - ulimit is the right command, but it has to be
executed as root, and it only applies within the running process.

| Hi Ken,
Thanks for the response. Its a small shop so I am the sysadmin and
developer. I'll take a closer look at ulimit.
