Io exception: Got minus one from a read call

I am getting this error Io exception: Got minus one from a read call.

This is happening on one of my connections on the database. After this message all adapter requests also fail. Does anyone have any information about this error please? Any information would be most welcome.

Could be a stale DB connection. Check your connection settings to see if the pool size (should be 0 in production) and the timeout setting is compatible with the DB timing out idle connections (the adapter should timeout an idle connection before the DB does).

Strange… I’ve got the same problem this morning !!! :eek:

One of our DBA said that these errors appeared in the Oracle log:

ORA-00020: maximum number of processes (%s)  exceeded
SP2-0640: Not connected ERROR:
ORA-00020: maximum number of  processes (%s) exceeded
SP2-0640: Not connected

So this tends to validate reamon’s answer (for my problem obviously) :slight_smile:

Hi,

I Got the same error, same messages at database side…
But the pool is at 0 and the timeout is the same as at database level - any other suggestions?

Thanks for the input!
