Interesting, I will have a look.
Seems like the gzipWriter for the auditRecords was closed. Do you see any log message related to that before the stack trace?
Did you send the process an OS signal?
The signal cleanup trap closes the gzipWriter, but should also exit the program immediately.
Also the obligatory questions: What OS, what version of OS, Golang and netcap did you use?
thanks for attention. i explain what happen
1- i compiled code on ubuntu 14 and run agent on abuntu 14. the agent work but when lot's of log send to collector i encounter this error.
2- i compiled on ubuntu 18 and have same problem
3- i run your release in hope to no problem would exist so i download the latest release and install libpcap-dev and musl and then execute collector and after a while have this problem.
4- as same of number 3 insted of linux i run windows version of release. i run exe file on windows 2012 and after some minutes i have same error.
i search internet and some one face this problem with other project but i couldn't realize what is exact problem?
so no i just have stack trace log. before i assign any argument for net.collect i have below error.
root@mylinux:/go# ./net.collect
panic: open : no such file or directory
goroutine 1 [running]:
main.udpServer(0xd0a0a0, 0xc000036278, 0xc0b5ef, 0xe, 0xcfa180, 0xc0004641e0)

main.main()
/go/src/github.com/dreadl0ck/netcap/cmd/collect/main.go:96 +0xf8
and as the release file it's EXE or ELF file i don't installed go ever. but for compile in my labtop i installed latest go version and after compile in dynamic or static linking library i have same problem.
at least which library i should installed ? could you write with exact version on linux and windows?
after encounter with log when i run it again all log that saved in root was deleted any idea to make another file ?
could you make a config file for log rotation cause i want to installed encap on at least 10 server.
any idea from you would be great.
thank for time.
Closed due to age.
If the problem still appears with the latest version, please open a new issue.
