Try using tshark from the command line and see if that works better.

Dear Support Members,

I have been facing a problem with the Wireshark sniffer for several times in the past month and I would like to ask your advise:

We are capturing data on one of are switches. We left the sniffer working for several days and when we came to check out the files we found out that it stop by itself few days earlier. The space hasn't run out on the local drive, the sniffer didn't stop working completely but only the capture stop.
Im pretty shure we have config the capture properly.
I have attached a screen shot of the capture configuration window & the app release.

The problem has reoccurred several times in the past and I don’t really know what can cause the sniffer stop capturing the data.

BR,

Asaf
