Java runtime error

[Leigh Peterson]

I am currently running WebLogic 5.1 sp9 on HP-UX 11 with HP SDK 1.3.0_01. I have tuned the kernel as perscribed in the HP Java Performance Tuning guide but I am receiving the following error in the WebLogic log:

"HotSpot VM warning: Cannot allocate alt signal stack"

Can someone please provide some information as to whether or not I need to further tune the kernel or if this is a known issue with this Java SDK.

Regards,
Leigh

It may not exactly be that it's old java, but newer java:

From the release notes at the bea site:

HP-UX SDK, for the Java (TM)) 2 Platform, Version 1.2.2.03

Please see http://www.unixsolutions.hp.com/products/java/index.html for information about the HP-UX SDK

Later,

Hi Leigh,

This warnings would indicate that we've failed to valloc() space for the alternate signal stack, which inturn indicates that we are very near to maxdsiz or were short of swap again.

You should increase your maxdsiz value.
