Continuing to see 'ORA-01652: unable to extend temp segment by 128 in tablespace TEMP_TBS' in rhn_taskomatic_daemon.log even after increasing temp tablespace

Issue

• Even after increasing the size of TEMP_TBS a number of times (as per this article), these errors are continuing to be seen in rhn_taskomatic_daemon.log:

INFO   | jvm 1    | 2012/12/18 08:28:00 | 2012-12-18 08:28:00,667 [Thread-58] INFO  com.redhat.rhn.taskomatic.task.repomd.RepositoryWriter - Generating new repository metadata for channel 'dev-up-serv-5-64-bit'(sha1) 717 packages, 8 errata

• The size of the temp tablespace was increased according to this article:
  https://access.redhat.com/knowledge/articles/290263

echo 'select count(*) * 0.0001 as "temp size (MB)" from rhnPackageCapability;' | sqlplus -S $(spacewalk-cfg-get default_db)

temp size (MB)
--------------
     1287.2956

• TEMP_TBS was increased to 1.3G but the problem continued. It was then increased to 3G but the problem is still occurring.
