Anybody else met the same issue? I just bumped the Cobalt porting from 22.lts.3 to 22.lts.6. Then meet a crash when running yts pages. Not often, only see twice during a month, but the stack are the same. It looks like cobalt is fetching some resources of web page, then the crash happened.
Program terminated with signal SIGSEGV, Segmentation fault.

I want to know if it's a known issue or someone else also met it.
