PO output For Communication email

[Roshan]

Hello,

suppliers did not receive email notifications only from 14:00 p.m to 14.30 p.m. Is there a way I can analyze the logs?

Thanks,
Roshan

you need to analyze workflow mailer logs.
It is publicly available information.

I have seen this anomaly in the interval 14:00 to 14:30 p.m

what does this null,0x1dc3e47,false,false,false means?

For other time it is like this:

These are arguments. You cant know what they mean, only the java getJDBCConnection knows them.

You cant analyze this that way.
You have to look for errors , failed attempts and similar things. You can make comments in every line where you see false.

İncrease the log level of workflow mailer , restart it and then analyze the trace and look for errors.
