Package: nscd Version: 2.7-18 Severity: important Hi,
I just upgraded nscd from version 2.3.6.ds1-13etch8 to 2.7-18 and it started using 100% CPU. In fact it starts using 100% CPU a few seconds after it was started. I tried to run it in debug mode (nscd -d), and it also starts using 100% CPU after a few seconds, without logging any activity. Note that is answers questions anyway, and log its activity fine. Running top with threads shown shows several nscd threads that use together 100% CPU: 4335 root 20 0 112m 2272 1716 R 11.2 0.2 0:19.02 nscd 4338 root 20 0 112m 2272 1716 R 11.2 0.2 0:03.04 nscd 4339 root 20 0 112m 2272 1716 R 11.2 0.2 0:43.08 nscd 4332 root 20 0 112m 2272 1716 R 10.6 0.2 1:12.14 nscd 4333 root 20 0 112m 2272 1716 R 10.6 0.2 1:12.18 nscd 4334 root 20 0 112m 2272 1716 R 10.6 0.2 1:17.18 nscd 4336 root 20 0 112m 2272 1716 R 10.6 0.2 0:26.56 nscd 4337 root 20 0 112m 2272 1716 R 10.6 0.2 0:44.26 nscd 4381 root 20 0 112m 2272 1716 R 10.6 0.2 0:00.88 nscd (The number of crazy nscd threads keeps increasing with time.) This finally makes my system unusable while nscd is running, so I have to stop it. This would certainly deserve grave severity if it affected everyone, but I can't believe it does and nobody reported the proble earlier. Hence, there must be something specific to my system. The problem might for example be powerpc-specific... FWIW, whenever I start it in debug mode, it first prints: 4244: invalid persistent database file "/var/cache/nscd/passwd": file size does not match 4244: invalid persistent database file "/var/cache/nscd/group": file size does not match 4244: invalid persistent database file "/var/cache/nscd/services": file size does not match If I remove those cache files, it does not print this, but does again the next time I start it.
