Hi,
Out transport service keeps crashing.
The key event in the log appears to be
"The following resources are under pressure:
Version buckets" (details below) After a while the service crashes and restarts.
We’ve reset the mail.que database by changing its location as per https://technet.microsoft.com/en-us/library/bb125177%28v=exchg.150%29.aspx?f=255&MSPPError=-2147217396
This has had no discernible impact on the situation.
We have adjusted EdgeTransport.exe.config to increase the VersionBucket Thresholds. We still max out.
We have identified a connector that had no size limit attached (this was an internal one) and most have a 100Mb limit. However the Queue Viewer tool does not show any messages at all in the queues. (earlier in troubleshooting, we would see messages in the queue viewer arriving in waves as clients and remote servers detected the transport service had become (briefly) available).
We have disabled the default receive connector (on port 25), and again no discernible impact.
Event Logs are below.
Any advice grateful received.
Thanks
Nick
