MSIR.0917 User's pushdown list overflowed during regular expression (process)

This message indicates that regular expression processing required more push down list space than was available. This message causes a user restart. Regular expression compilation and evaluation is highly recursive and so can use large amounts of push down list space. Probably the best thing to do in this situation is to increase the amount of push down list space available to the application by using the UTABLE command to increase LPDLST. Of course, like all table size increases, this might require juggling other table sizes down or increasing the size of the servers.
