What triggered this post ? I've spent the past two days installing and configuring Lotus Quickr Services for WebSphere Portal v22.214.171.124 on a Red Hat Enterprise Linux VMware image.
No major problems *until* I ran into a "Too many open files" error within SystemOut.log. I saw this when I was navigating the Quickr environment.
This rang bells from way back in 2001 when I was first playing with WebSphere Application Server on various flavours of Unix. The fix was always to increase the OS' file descriptor limit which, on Linux, is done using the ulimit command.
Well, I thought to myself - surely I can't be the first person to find this with Quickr which is, after all, based upon WebSphere Application Server ?
Then I remembered an email exchange from a colleague, Rob H, who'd pointed this out as one of the "gotchas" with Quickr on Linux.
I checked the Information Centre here and, lo and behold, found: -
Setting File Descriptor Limit
Never mind, I've increased the limit, rebooted for good measure, and restarted Quickr.
One lives and one learns ....
Happy New Year
