[crit] (28)No space left on device

[Vikrama Sanjeeva <viki.sanjeeva@xxxxxxxxx>]

Hello everybody,

 I am getting below error on Apache/2.2.11 (Unix) running on Solaris 10 production machine:

"[crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock"

I have checked device space on which apache is installed and its fine:

@machine: /usr/local/apache2/bin> df -h /usr
Filesystem             size   used  avail capacity  Mounted on
/dev/dsk/c1t0d0s0       79G   9.6G    68G    13%    /

After googling this error I tried below commands, but no success:

ipcs -s | grep www   [returned nothing]


Please guide why this error is coming and what its permenent resolution.
