Description of problem:

Installed Sat 530 on s390x.   I noticed that the repo files were not being generated for al channels, looked at taskomatic logs and saw OutOfMemoryError


Intially I only synced rhel5 i386, repo files were generated for that.
Second I synced x86_64 & s390x.  Now I see OutOfMemoryError


Version-Release number of selected component (if applicable):
Satellite-5.3.0-RHEL5-re20090625.0-s390x-embedded-oracle.iso

How reproducible:
Only tried on one install, but it consistently gets OutOfMemoryError about 10 minutes after taskomatic restart

Steps to Reproduce:
1. Install s390x
2. Sync RHEL 4/5  {s390x, i386, x86_64} including proxy 5.3 and rhn-tools
3. Register a rhel5 x86_64 machine, do a yum install zsh...see repo failure
4. Register a s390x machine, do a yum install zsh...see repo failure

  
Actual results:
Look at taskomatic logs on server.  It might be ~10 minutes or so, taskomatic fails from OutOfMemory.

Expected results:
After period of time repo files get generated.

Additional info:

I bumped the configured java memory and restarted taskomatic and it looks better.  Below is the change I made.

/etc/rhn/default/rhn_taskomatic_daemon.conf
# Initial Java Heap Size (in MB)
#JWM Change 6/30/09, to fix out of memory error with repogen
#wrapper.java.initmemory=32
wrapper.java.initmemory=256

# Maximum Java Heap Size (in MB)
#JWM Change 6/30/09, to fix out of memory error with repogen
#wrapper.java.maxmemory=192
wrapper.java.maxmemory=1024




This is the original error I was seeing with OutOfMemoryError
