[NiteWave]

are you using the latest 4.2.2 ?

check when you installed 4.2.2:
#ls -l /usr/local/lsws/bin/lshttpd.4.2.2

pls send download link to the core files to bug@ for investigation.

I also have the same problem.

It helps to set:
Enable Request Filtering: No
Scan Request Body: No
(both of them)

Broad assumption. Our clients run software from their file servers that require weekly reboots. The software actually reports how many days it's been since the DB server was rebooted and complains after 7 days Speed Test https://vidmate.bid/ .

Rather than having a whole new server for their DB, we run it on the FS and reboot weekly.
