Growing System Dump Device usage with HPOS on AIX

Configuration: AIX 5.2, maintenance level 1 and Dazel 3.3, Service Pack 9.
Problem: sysdumpdev -e shows increasing usage of the system dump device. Eventually the dump device needed, grows to 1200 MB, after which the server becomes unresponsive and a reboot is the only solution.

Even though HP suggests using maintenance level 1 for AIX 5.2, try using maintenance level 2; after loading ML2, this problem is gone; it's an AIX bug with a memory leak in the TCP/IP stack, which is solved in ML2.
