HPOS 3.5 Solution for Unknown Status Occurring on Overloaded Servers

6 HP Output Server 3.5
Solution for Unknown Status Occurring on Overloaded Servers
Conclusion
This command forces the HP-UX heap manager to use a single ARENA. So when the CM server is run, the first
pdconfig -d command invocation raises the memory size of the CM server from 14MB to 58MB while the
subsequent pdconfig -d invocations do not raise the memory size above 58MB.
NOTE: The use of the _M_ARENA_OPTS environment variable is described in the HP-UX malloc
man page.
Conclusion
The servers buffer all the output for a given command operation in their memory prior to marshalling the data to the
server client. This causes the servers to fail when the number of jobs is large. The only way to avoid the failure is to
increase the data segment size (this can only reduce the probability of server crash) or avoid issuing a command on
any batch of jobs.
