I tried to make dovecot with configure --with-ioloop=select and same result: [skipped] pollsys(0xFFBFF888, 8, 0xFFBFF950, 0x00000000) = 1 pollsys(0xFFBFF4D8, 5, 0xFFBFF458, 0x00000000) = 0 pollsys(0xFFBFF4D8, 5, 0xFFBFF458, 0x00000000) = 0 pollsys(0xFFBFF888, 8, 0xFFBFF950, 0x00000000) = 1 pollsys(0xFFBFF4D8, 5, 0xFFBFF458, 0x00000000) = 0 pollsys(0xFFBFF4D8, 5, 0xFFBFF458, 0x00000000) = 0 [skipped to forever] and 100% of CPU time.
May be problem is in select() (poll() ?) call with unnecessary file descriptor, who always ready (may be connection to LDAP server?) ?
