Hello,

we have encountered a very strange behaviour of HornetQueue, running  
it

inside vz results in:

bash: fork: Cannot allocate memory
or
 xmalloc: cannot allocate 4008 bytes (2084864 bytes allocated)

( this is on host node, that has ~20G of free, unused RAM, inside

containers the problem is not visible - hornet is limited to ~4G of  
ram,

container is limited to ~16G of ram and 0 vSwap, rest is unlimited )


UBC inside container shows no visible resource usage problem, I'd go  
as

far as to call it frugal - 1600 filedescriptors, very low shm usage,

physpages nowhere near limit, and yet, when daemon runs, HN is  
unable to

even accept login from console.

how can I track down what is causing this?

regards, Eyck
