memory leak on hobbitd_channel ?

[nico]

Hi, 

On my hobbit server, i got lot of memory used by hobbitd_channel (4.4g =
74% of all the memory ). 

Tasks: 177 total, 14 running, 162 sleeping, 0 stopped, 1 zombie 

Cpu(s): 20.6% us, 3.2% sy, 0.0% ni, 32.9% id, 42.9% wa, 0.2% hi, 0.3% si 

Mem: 6107804k total, 6059264k used, 48540k free, 195772k buffers 

Swap: 4194288k total, 4194252k used, 36k free, 209976k cached

My questions: 

- is it normal that hobbitd_channel takes so much memory (4.4Gb). 

- Is it possible to decrease it ? (kill ? ) 

- Is it possible to know why it's taking so much memory (strace ?) 

With strace on it, i only see this things: 

write(4, "@@status#902860|1238227571.36674"..., 486) = -1 EAGAIN (Resource
temporarily unavailable) 

nanosleep({0, 2500000}, NULL) = 0 

semop(9666576, 0x7fbfffe460, 1) = 0 

rt_sigaction(SIGALRM, {0x402140, [ALRM], SA_RESTORER|SA_RESTART,
0x2a9569a300}, {SIG_IGN}, 8) = 0 

alarm(2) = 2 

semop(9666576, 0x7fbfffe460, 1) = 0 

rt_sigaction(SIGALRM, {SIG_IGN}, {0x402140, [ALRM],
SA_RESTORER|SA_RESTART, 0x2a9569a300}, 8) = 0 

semop(9666576, 0x7fbfffe460, 1) = 0 

write(4, "@@status#902860|1238227571.36674"..., 486) = -1 EAGAIN (Resource

nanosleep({0, 2500000}, NULL) = 0 

semop(9666576, 0x7fbfffe460, 1) = 0 

rt_sigaction(SIGALRM, {0x402140, [ALRM],
SA_RESTORER|SA_RESTART,
0x2a9569a300}, {SIG_IGN}, 8) = 0 

alarm(2) = 2 

semop(9666576, 0x7fbfffe460, 1) = 0 

rt_sigaction(SIGALRM, {SIG_IGN}, {0x402140, [ALRM],
SA_RESTORER|SA_RESTART, 0x2a9569a300}, 8) = 0 

semop(9666576, 0x7fbfffe460, 1) = 0 

write(4, "@@status#902860|1238227571.36674"..., 486) = -1 EAGAIN (Resource
temporarily unavailable) 

nanosleep({0, 2500000},  
 ----> it s writing status. (?) 
 Here the status statistic (bbgen): 
  bbgen for Hobbit version 4.2.0 
 Statistics:  Hosts : 8910  Status messages : 70987  Purple messages : 0 
Pages : 29  

 Any idea about memory is welcome !  

Thanks, 

Regards,
