Solaris11 ( sparc ) agent crash after some time.

[Pigi-102]

Hi,
we are trying to use ncpa on Solaris 11.4 on sparc but after starting it it runs fine for an hour or less and then in crash.

I've "trussed" it and can see that whenit crash this is the output from the truss:

Any idea on what to look ?

Thanks

Hello, did you ever get this working? Unfortunately I'm not very familiar with Solaris, so I don't really have many ideas as to why it'd be crashing - generally if there's a random crash it'd be because it's unable to handle something like a drive disappearing or something changing that it doesn't expect.

I can confirm this issue on 2 SPARC S7-2L running Solaris 11.4

One fails with same trace above, while another one fails with:

One week after downgrading NCPA to version 2.3.1, it has not crashed.

Seems to be a problem with version 2.4.0.
