INFORMIX SERVER / 5725A3900 / E10 - 

onpsm -D add, for CLOUD and STDIO device types, supports an
optional '--max_part_size ' parameter whose value
can either carry a b|k|m|g|t|p unit qualifier or it would
(should) assumed to be a size in kB.

Version 14.10.xC7 unfortunately assumes MB instead of kB, which
not only can lead to much bigger than intended entities sent to
backup storage, but also could cause backup failure like this:

bar_act.log:
 2021-12-10 17:46:49.036821 12823  12821 Begin level 0 backup
rootdbs.
 2021-12-10 17:46:49.039553 12823  12821 Successfully connected
to Storage Manager.
 2021-12-10 17:46:49.042338* 12823  12821 (-43080) Process 12823
received signal 13. Process will exit after cleanup.

psm_act.log:
 2021-12-10 17:46:49.041715 12823  12821 REST ERROR: received
more data than promised. used + tsize = 222 > buffer size(0).

This "buffer size (0)" would be the result of e.g.
'--max_part_size 102400' getting stored as 10GB (107374182400)
in PSM catalog device table which, as a four byte integer, would
simply be zero.

Simple workaround: do specify intended unit character when using
--max_part_size option, e.g. '--max_part_size 102400k'.
