Error running WLS on HPUX: No buffer space available

Hello,

I am running WebLogic Server on an HPUX 11.0 box. I am getting intermittent crashes of the WLS application(JVM 1.2.2)with the following error. The exact error messages are as follows:

I have scoured the doc and forums and note that this error is related to TCP/IP. However, I don't know what the solution is.

Has anyone had this problem before, and if so, what was your solution?

Thanks,

Are you running weblogic 5.1 Service pack 10? Or Weblogic 6.1???

Are you running 11.00/32 or 11.00/64?


Also, make sure you have the latest OS patches for 11.00

Harry,

I am running WLS 5.1 SP6. I am also running 11.00 / 32.

I have gone through the kernel tuning process, which included updating to a list of patches. I have installed those patches. I will check your link to see if there are others that I should also install.

We upgrade to SP10, because of some issues we had with SP6. I'd suggest upgrading to SP10.

Harry,

Upgrading to SP10 is not an option at this time, as our app is running on five different OS platforms.

Is there some environment switch that can increase this buffer space?

[harry d brown jr]

Steve,

How many tcp connections are being made when it dies?

Harry,

I am an HPUX newbie, so bear with me. How would I find out that information?

You can install "lsof" from:

http://hpux.ee.ualberta.ca/hppd/hpux/Sysadmin/lsof-4.55/

then you run it "lsof -i" and it'll flash by all of the network connections.

The problem we faced was the same as yours. We hit a wall of about 35 users when things hit the fan. The only solution I can recommend is to upgrade to sp10 or 6.1.
