mmap failed

# ./java --version
/usr/lib/dld.sl: Call to mmap() failed - TEXT /opt/java1.4/jre/lib/PA_RISC2.0/server/libjvm.sl

Can someone help with this error?

Thanks

swap looks ok too

hmm, I would be really surprised if your max data and text segment sizes are too small. But doesn't hurt to check.

# kmtune | egrep "dsiz|tsiz"

Post what you get.

[brian_31]

# kmtune | egrep "dsiz|tsiz"
maxdsiz 1073741824 - 1073741824

Your dsize and tsize seems to be good enough.

For the lack of other responses, I can throw some wild guesses :-).

Is this Java by HP or some other vendor ? In other words, did you install the product using swinstall ? If yes, you could try a swverify to make sure you dont have a corrupt .sl.

[Dennis Handly]

Since your message says "Call to mmap() failed - TEXT", you are short on shared memory, not swap space.

What does the following show:
$ ipcs -ma

Any large segments?

I have the same problem here. Would you able to help.

Your Java code is probably 32bit and is competing with all other 32bit processes for the single shared memory map. While there may be enough in the shared memory map for all your processes, it has become fragmented and none of the pieces is large enough. This usually comes from randomly shutting down various processes or worse, using kill -9. A reboot will likely fix the problem, or possibly, a graceful shutdown of the database and applications, check ipcs -bmop to see if there are any orphaned segments. Then start the processes again.
