[tao-bugs] Odp: Re: Odp: Re: tao imr locator seg fault

[Tomasz Mikolajczyk]

Hi,

I do not use the select based reactor because of its max opened file descriptors limit, but for the sake of testing I can check if the issue is reproducible with select reactor. 

The decision about using commercial support or not is outside of me. Anyway, I think that commercial support is rather for addressing customer's questions rather than fixing a broken code which may hit any other ACE-TAO user, so I thought that being aware of that issue would be important for you.

Regards,
Tomasz Mikolajczyk
