Intermittent SSH issue: "ssh_rsa_sign: RSA_sign failed"

Some of our automated jobs that use SFTP to transfer files between servers are hitting an occasional error:
ssh_rsa_sign: RSA_sign failed: error:8107107D:lib(129):func(113):reason(125)
Received message too long 1651074911
ssh_askpass: exec(/usr/lib/ssh/ssh-askpass): No such file or directory
Write failed: Broken pipe

The connections in question are initiated on a Solaris 10 system (1/13 s10s_u11wos_24a) using Sun_SSH_1.1.5, and are received by a Solaris 9 server (9/04 s9s_u7wos_09) using OpenSSH_3.7.1p2.

I'm unable to actually duplicate the issue manually, it only happens very occasionally as part of the batch jobs; there are 7 jobs that transfer various things and one of them will fail on one day, and then everything will run fine the next day, and then another job will have a problem on another day.  It's entirely random.  One job does seem to have issues slightly more frequently than the others but the sample size is so small there's little statistical validity to it.

Howdy, Stranger!
