[LDM #FLA-146766]: ldm file writes



Steve,

Actually, an "ldmadmin pqactHUP" should cause every pqact(1) process to
receive a SIGHUP.

The operating system determines what a "flush" means. Did you upgrade yours
recently?

I don't see how. I just examined the code and the processing of the "-flush"
option is, effectively, the same for both the FILE and STDIOFILE actions.

It's a mystery.
