During heavy load, the Microsoft Exchange Message Transfer Agent (MTA) may
report the following error:
Event 9234: MSExchangeMTA Operating System
A sockets error BASE IL on a select() call was detected.
The MTA will attempt to recover the sockets connection.
Control block index: 10038. [TCP/IP ASYNC 11 280 %6] (12)
The MTA will continue to transfer messages.
CAUSE
This is a non-critical error that most often shows up when the MTA is
processing a high number of messages and/or on multi-processor servers. The
sockets error, 10038, indicates that the MTA has attempted to open an
invalid socket. As soon as another MTA thread releases a socket, the MTA
thread in error will claim and use it.
No data loss will occur as this activity is by design under heavy load. For
more information on the 10038 sockets error, please see the following
