Logstash works well with an error

Elastic Stack Logstash
1

I used the logstash with the version of 5.6.3, after a few time later. there is an error message in logs/logstash-plain.log. the error is :[ERROR][logstash.filters.ruby ] Ruby exception occurred: Regexp Interrupted. but my logstash is still work. does this a matter?

the whole logs is:

due to no other error messages, how can I debug this error?

It looks like you have a ruby filter that's taking too long to filter events. Without knowing anything about your configuration that's really all I can say.

you mean that there are some low efficiency ruby code in my conf files?

there are 5 ruby code in my conf files .

That would've been my guess, but your ruby filters seems pretty straight-forward so I don't know what's going on.

now, more errors comeout:
