Question UNIX memory problems w/Progress DB

We are currently running HP-UX 11 as our database server. The database is Progress version 9.1C.

As of late, some of our batch processes that run on the UNIX db server are erroring out because of what appear to be memory issues(at least according to Progress). The db error messages indicate that either there are too may subprocesses and it cannot fork, there is not enough memory to execute the request, or there is not enough memory to allocate a sort buffer. There does not appear to be a consistent pattern to when this happens. Also, we don't appear to be exceeding swap space.

Not sure what else it could be. If any of you have encountered similiar problems, how did you resolve it? Any and all feedback is appreciated.

datacopy - move table data between two servers SYNOPSIS
datacopy { -t | -a | -c owner } [-b batchsize] [-p packetsize] [-v] [-d] [-S server/username/password/database/table_or_view] [-D server/username/password/database/table] DESCRIPTION
datacopy is a utility distributed with FreeTDS. datacopy will move table data from one server to another without the need for intermediate files. datacopy is much faster and more efficient than is freebcp out/in. datacopy makes use of the db-lib bcp API built into FreeTDS. This API is also available to application developers. datacopy can be used to migrate data between Sybase ASE and SQL Server or vice versa. OPTIONS
-t Truncate target table before loading data. -a Append data to target table. -c owner Create the target table with the same schema as the source table. datacopy will submit a 'create table' command on the target server/database using the specified owner in the command, e.g. CREATE TABLE owner.table (...). -b batchsize The number of rows per batch of data copied. Each batch of data is effectively 'committed' to the database. The default is 1000. -p packetsize The number of bytes, per network packet, sent to and from the servers. Increased packet size can enhance performance. -v Produce verbose output, including diagnostic timings. -d Produce freetds TDSDUMP output. (Serious debug only!) -S server/username/password/database/table_or_view The connection information for the source server and the location/name of the table (or view) to be copied. If not specified, data- copy will prompt the user for the information. -D server/username/password/database/table The connection information for the destination server and the location/name of the target table. If not specified, datacopy will prompt the user for the information. SEE ALSO
