I am running OpenSuSE 11.1 and have experienced a strange phenomenon these past few days. At unpredictable times my desktop freezes for a few seconds, then flashes and comes back to life. Sometimes this happens only once or twice, but there have been cases where it stopped me working for 20 minutes.

The only things I can see is the following message in one of my shells:
kbuildsycoca running...

Today this was followed by these messages (which may be unconnected):

DCOP Cleaning up dead connections.
X Error: BadWindow (invalid Window parameter) 3

Resource id: 0x3800053
X Error: BadWindow (invalid Window parameter) 3
Major opcode: 20
Minor opcode: 0
Resource id: 0x380029d


Can anyone please advise why this is happenning and how to stop it?

Thanks,

Abe
