SCCM: SUP is not working due to WSUS crash

Interesting case – WSUS built for SCCM SUP crashed regularly. It started from once in a month, after that more and more often and finally WSUS application pool could not stay and hour. Recommended solution was to recycle WSUS application pool. But that was not really a solution since permanent monitoring is required.

It turned out to be a known issue for SCCM 2012 (looks like SCCM CB is affected too) and Microsoft recommends to enlarge App Pool private memory to 4 (or in some cases to 8!) GB. Sounds a bit crazy for me but at least WSUS is up and running now.
