Camera discovery plugin leaks memory

Affected platforms

exacqVision 6.4 or higher

<br>

Symptom

Every time there is a config or alarm event from core, the IP camera detect plugin (IPCamDetectPI.dll) will leak memory. The memory leak is in small increments and on systems where huge number of events are happening, like lots and lots of motion events for example, the leak can grow to a few megabytes per day.

<br>

Work Around

No single work around that covers all cases. On certain cases like Onvif, minimizing the motion events by removing the json file entry to prevent motion events can mitigate the issue a lot.

Internal memory leak when sending email

Affected platforms

exacqVision 4.12.3 to 7.0

Symptom

There is a small memory leak whenever the server executes a program. This leak is unlikely to cause a problem on any desktop systems, but it could cause a hang or reboot on Edge systems with limited memory, if the Edge server is configured to send frequent emails.

<br>

Workaround

Disable email notifications

Resolution

Fixed in exacqVision 7.2

Exacqd handle leak

Symptom:

It is possible after a very long period for the server to stop functioning, requiring a restart.

Problem:

There is a slow handle leak in exacqd introduced in server version 9.5.25/9.6.0. This handle is never used, so a slow memory leak is the result. 

Windows has a limit of 16 million handles. A server that leaks 3 handles a minute would take 4 years to hit this limit. A server with many LDAP users always connected would hit this limit sooner. 

Solution:

Current workaround is to downgrade to 9.4. Future versions should include fix.
