pdm_mail_nxd unexpectedly crashes intermittently
The possible reasons for this unexpectly intermittent process crash can be: memory leak or any corrupted message.

Intermittent email processing issues with PDM_MAIL_NXD.


As workaround, monitor the process and run a pdm_d_refresh, in case it's not running.
Also we can recommend to increase the mail_max_threads to 40, as recommended in the KB:
