pagespeed module?

[MyWay]

It seems it's not working...

[gplessis]

Please provide more details: distribution, versions, configuration, logs, error messages...

[MyWay]

Debian Jessie
nginx version: nginx/1.10.3
built with OpenSSL 1.0.1t 3 May 2016 (running with OpenSSL 1.0.2k 26 Jan 2017)
If I enable pagespeed module, nginx crashes with worker process "exited on signal 11" and watching to its trace, there is an error related to third_party/serf/instaweb_response_buckets (seems it can't find the file/directory), if you want the entire trace I can post it.

Any news about it?

[gplessis]

Could you please retry with the Nginx 1.12+ packages for Jessie with an updated Pagespeed module and share your feedback?

[MyWay]

Sure I will, thank you very much.

[MyWay]

Still crashing. Do you need the trace?

[gplessis]

Please.

[MyWay]

It seems fixed with the last release. I will let you know if I see anything.
