Question about mysql error received "[ERROR] Error in accept: Software caused connect

I am running mysql v5.0.22 on a Sparc Solaris 8 server. I'm using an innodb storage engine and I run
replication to another remote SOlaris 8 server running the same version of mysq.


Today I was alerted to an error in the logs. This is the only error and it did not seem to effect replication.

130417 23:30:08 [ERROR] Error in accept: Software caused connection abort

I cannot find much on this error and wondered it anyone can assist.

Thanks so much;
