Have you ever faced it? Do you know why it happens? Do you know if there is any bug related?

Thanks!

This is an internal error and should be reported to Oracle.. the root maybe at OS level or this might also be due to physical data block corruption.. but it is recommended that you log a SR with oracle

   This is an internal bug and according to bug If DCD is enabled (sqlnet.expire_time set in sqlnet.ora) then
shared server or dispatcher processes may occassionally dump with a stack showing "sigacthandler" and "nstimexp" functions. This is fixed in 10.1.0.5 and 10.2.0.3.
