Varnish panics

[יריב הראל]

Start up  params :

DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT} \
             -f ${VARNISH_VCL_CONF} \
             -T ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT} \
             -t ${VARNISH_TTL} \
             -w ${VARNISH_MIN_THREADS},${VARNISH_MAX_THREADS},${VARNISH_THREAD_TIMEOUT} \
             -u varnish -g varnish \
             -S ${VARNISH_SECRET_FILE} \
             -s ${VARNISH_STORAGE} \
             -p sess_timeout=305\
             -p http_req_hdr_len=16384 \
             -p http_req_size=65536 \
             -p http_resp_hdr_len=16384 \
             -p http_resp_size=65536 \
             -p http_gzip_support=off \
             -p pipe_timeout=120 \
             -p sess_workspace=131072 \
             -p http_max_hdr=256"


The strange thing is that this is only happening on 1 varnish server of 3

Maybe some related to sess_workspace and http headers ? the web site has some vary unusual cookies and other headers regarding size

Thanks

Hi ,
