[squid-users] High CPU load; debug log shows tight loop: storeDiskdDirRebuildFromSwapLog ... new_StoreEntry ... storeDirSwapLog ... diskHandleWrite

I'm observing very high Squid CPU load, which negatively affects performance.

Enabling debug_options ALL,9 for a few seconds shows this extremely
frequent loop -- Squid is doing only this millions of times:

2010/01/07 12:29:23| storeDiskdDirRebuildFromSwapLog: SWAP_LOG_ADD

2010/01/07 12:29:23| diskHandleWrite: FD 8 writing 193 bytes
2010/01/07 12:29:23| diskHandleWrite: FD 8 len = 193

Any idea what might cause this?
