> Is there anyway to capture the stderr output > of a program to which LDM products are being > PIPED? No because such decoders are executed by the pqact(1) process, which is executed by the LDM server, which is a daemon process and for which the standard output and standard error streams do not exist. Consequently, decoders must make arrangements for logging messages. They can use the ulog(1) facility that comes with the LDM package, or, if the decoder is a script, the ulogger(1) utility that also comes with the LDM package, or the logger(1) utility that comes with the operating system.
