Hi, So, the actual problem you are talking about is that the dumpcap process stopped unexpectedly? This is uncommon unless there are external factors in play, e.g. , a network interface went down, the output file got (re-)moved before complete, the OOM killer kicked in. If you can find evidence of this, that might explain it. Was it a one time occurrence, or a reproducible event? This would allow further study of the conditions. Thanks, Jaap

However, I have a script that controls the hard disk space. It won't exhaust the storage. I have used the same setup with tcpdump since the last couple of years. But I had to deal with another network interface, that is why I decided to use dumpcap or tshark. I will not let go the storage space beyond 90% of it. Fully controlled. -b duration:15 --> jump to a new dump, likewise, it continues. usually, PCAP file size is 70-75MB and once compressed it will be 18-20MB. anyway, the issue that I have faced with dumpcap was really unexpected. Even there is nothing in the man pages to have a try. I was looking for a guidance. if anyone out there who has faced this problem before.

You’re running it in multiple files mode. It is supposed to work this way. You may want to consider adding -b files:<value> to define the number of capture files to store to prevent exhausting your storage. If configured this way you can indeed run it for an extended period. Personally I’ve run it for a couple of months on a production network like this.

May I know is there a way to resolve this issue? I wanna run this command continously, days or months or years... until the process stoped manually.
