Resolution

Please edit /etc/rhn/rhn.conf and add the option

taskomatic.java.maxmemory = <value>

manually to the end of the file. The value has to be entered in megabytes. An example could be:

taskomatic.java.maxmemory = 4096

When done, restart taskomatic using

rctaskomatic restart

to have it pick up the new XmX value. Since the last releases, the default value was set to 4096, so this change should not be needed any more in new releases. Higher values should not be required either, as recommended in the past (not even when using Expanded Support channels). The general RAM requirements still apply (32 GB for a production system).

Additional Information

NOTE: As of SUSE Manager 3, the option is no longer called taskomatic.maxmemory but taskomatic.java.maxmemory.
