Well, in case of pdnsd the chroot is /var/empty/ and it is supposed to be empty, so this contradicts the need to copy a library... В Сизифе теперь тоже падает pdnsd с сообщением в логе. pdnsd[1220]: segfault at 0 ip 0000003a50a77de1 sp 00007ffdca940d90 error 4 in libc-2.27.so[3a50a22000+146000] Может быть это тоже самое. |
pdns-1.2.7 crashes some time after the start because libgcc_s is missing in /var/empty (its chroot). Its error message before dying is: libgcc_s.so.1 must be installed for pthread_cancel to work Here are some last messages from running: strace -e trace=file -fF pdnsd -g -v3 --config-file /etc/pdnsd.conf -p /var/run/pdnsd.pid 52 01/11 00:44:00| Using cached record. 52 01/11 00:44:00| Starting cached resolve for: ibigdan.livejournal.com., query AAAA 52 01/11 00:44:00| Record found in cache for ibigdan.livejournal.com. 52 01/11 00:44:00| Requery decision: dflags=0, cflags=0, req=0, neg=0, timed=1, timestamp=0 52 01/11 00:44:00| Trying name servers. 52 01/11 00:44:00| Sending query to 174.35.55.22 52 01/11 00:44:00| Sending query to 66.114.55.22 52 01/11 00:44:00| Caching type AAAA for domain ibigdan.livejournal.com. negative with ttl 600 52 01/11 00:44:00| Query to 174.35.55.22 succeeded. 52 01/11 00:44:00| Outbound msg len 103, tc=0, rc="no error" 52 01/11 00:44:00| Answering to: 192.168.1.13, source address: 192.168.1.2 Process 6227 detached 4 01/11 00:44:11| No query succeeded.
