TCPTerminatedReadTimeoutExpired

Tiffany Raczynski · Aug 1, 2018

I am receiving this alert every couple of minutes. I am trying to figure out what is causing this and if it is just the settings on my TCP operation or if this indicates an actual issue. Is it an issue with my framing (MLLP) or reply code actions (not set)? Something else?

Error:

ERROR <Ens>ErrTCPTerminatedReadTimeoutExpired: TCP Read timeout (30) expired waiting for terminator SegTerminatorAscii=13, on |TCP|7049|12692, data received =''
(alert request ID=2071)

Screenshot:

Here are the settings on my operation:

Class Name	EnsLib.HL7.Operation.TCPOperation
Stay Connected	5
Connect Timeout	5
Reconnect Retry	5
Get Reply	True
Response Timeout	30
Read Timeout	5
Framing	MLLP
Pool Size	1
Save Replies	All
Default Char Encoding	latin1
Retry Interval	5
Failure Timeout	-1
Throttle Delay	0
Alert Retry Grace Period	30
Queue Count Alert	30
Queue Wait Alert	60
Alert On Error	True
Inactivity Timeout	0

Anyone else ever have this? If so, any suggestions on how to address/handle it?

This typically means that the remote system has failed to send an HL7 ACK back within 30 seconds. If it is common for that system to take awhile to respond, you can increase "Response Timeout" from 30 sec to a higher value.

Thank you Alex. This is helpful and makes sense.

One of the obvious things I didn't catch while looking at this error is that we were actually queuing messages to them. I realized that after the fact, but still didn't know if it was due to framing or simply not receiving data back. Appreciate the insight!
