MQ mainframe channel drop problem

Please have Mainframe support investigate why the MQ Series Channel are failing. This problem has not occurred in the past but this week we have had 2 separate instance where the Mainframe MQ Receiver Channel was stuck I a "run" state and had to force stopped to regain connection to the remote system.
The below is an extract from the remote system MQ Series log for today's problem.

AMQ9208: Error on receive from host ccs100 (172.16.12.20).
EXPLANATION:
An error occurred receiving data from ccs100 (172.16.12.20) over TCP/IP. This
may be due to a communications failure.
ACTION:
The return code from the TCP/IP (recv) call was 10054 (X'2746'). Record these
values and tell the systems administrator.

AMQ9999: Channel program ended abnormally.
EXPLANATION:
Channel program 'WAOLP.MQMP_WAO.00' ended abnormally.
ACTION:
Look at previous error messages for channel program 'WAOLP.MQMP_WAO.00' in the
error files to determine the cause of the failure.

AMQ9002: Channel 'WAOLP.MQMP_WAO.00' is starting.
EXPLANATION:
Channel 'WAOLP.MQMP_WAO.00' is starting.
ACTION:
None.

AMQ9202: Remote host 'ccs100-mq.wao.alcoa.com (172.16.12.20) (1414)' not
available, retry later.
EXPLANATION:
The attempt to allocate a conversation using TCP/IP to host
'ccs100-mq.wao.alcoa.com (172.16.12.20) (1414)' was not successful. However
the error may be a transitory one and it may be possible to successfully
allocate a TCP/IP conversation later.
ACTION:
Try the connection again later. If the failure persists, record the error
values and contact your systems administrator. The return code from TCP/IP is
10060 (X'274C'). The reason for the failure may be that this host cannot reach
the destination host. It may also be possible that the listening program at
host 'ccs100-mq.wao.alcoa.com (172.16.12.20) (1414)' was not running. If this
is the case, perform the relevant operations to start the TCP/IP listening
program, and try again.
