saslauthd loops sometimes (cyrus-sasl 2.1.26)

Hello.

saslauthd loops sometimes. 

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
 7365 root      20   0   53080      0      0 R 29.89 0.000 357:37.26 saslauthd

14582 root      20   0   53080      0      0 R 28.56 0.000 331:47.78 saslauthd
14583 root      20   0   53080      4      0 R 28.23 0.000 331:47.68 saslauthd
 7366 root      20   0   53080      0      0 R 27.90 0.000 357:23.28 saslauthd
 7371 root      20   0   53080      4      0 R 27.90 0.000 357:39.20 saslauthd
 7364 root      20   0   53080      0      0 R 26.24 0.000 357:48.34 saslauthd

strace for pid 7364 for example:

read(5, "", 949)                        = 0
select(6, [5], NULL, NULL, {0, 0})      = 1 (in [5], left {0, 0})
read(5, "", 949)                        = 0
select(6, [5], NULL, NULL, {0, 0})      = 1 (in [5], left {0, 0})
read(5, "", 949)                        = 0
select(6, [5], NULL, NULL, {0, 0})      = 1 (in [5], left {0, 0})

saslauthd ran with "-a rimap -O imap.server -r -n 0". Has anyone met with this
problem ?
