What does truss report the verbose arguments to pollsys to be?
eg:
# truss -v pollsys -p `pgrep dovecot-auth`

Here is my output from truss:

The timeout values in the large block change from truss-call to
truss-call, the
highest values are round about 2.0 sec ... but in many truss calls no
times 0 (zero)
seconds, just in the short block
