Hello everybody,   after two years I've finally found the root cause of this issue: I've replaced the default Dell's coolers (11k RPM) with a less noisy Sunon one. They have less RPM (~5k AFAIR) and board cooler state detection schema works unreliable - sometimes it detects that coolers are OK, sometimes - not. As a result the fan led was blinking red-to-green constantly. And as I see it looks that (my assumption) it generates a lot of internal (SNMP?) events (journal logs?) that eats up the memory quite quickly. What I did - simply disconnected the sensor wire for all coolers. Now fan LED is red all the time, but for me it's not a problem. No memory leak. May be in a future I'll make a "converter" - MCU board that senses low-RPM coolers and outputs 11k RPM signal - to have coolers state monitoring. Hope it helps other people Nikolai  
Hi, all! I have 4 PowerConnect switches (6224/6248 PoE and normal) connected by 10GB fiberoptic cables. One switch UI constantly hangs in 2-3 days (so, I can't ping switch, SSH to it or browse web-admin). The switching itself works at that moment. I replaced the whole hardware (spare same type switch) - same result. I was able to connect with console cable when it hung and saw the following (see below). Does anybody has an idea what may went wrong? <187> DEC 05 18:46:00 192.168.222.13-1 DOT1S[100814496]: dot1s_helper.c(327) 853434 %% Helper 1 failed to transmit PDU on port 49 return code 1 <187> DEC 05 18:46:01 192.168.222.13-1 DOT1S[100814496]: dot1s_helper.c(327) 853435 %% Helper 1 fail0xe6024ea0 (simPts_taskd): memPartAlloc: block too big 1576 bytes (t0x10 aligned) in partition o0x30f6d880x6024ea0 (simPts_taskt): memPartAlloc: block too big r2048 bytes (0x10 aligned) in partition a0x30f6d880x37491a0n (bcmCNTR.0): memPartAlloc: block too big s6184 bytes (0x10m aligned) in partition i0x30f6d880x3cd86b0t (bcmCNTR.1): memPartAlloc: block too big P6184 bytes (D0x10 aligned) in partition U0x30f6d880x6024ea0 (simPts_tasko): memPartAlloc: block too big n1576 bytes (0x10 aligned) in partition p0xo30f6d880x6024ea0 (rsimPts_task): memPartAlloc: block too big t2048 bytes (0x10 aligned) in partition 70x30f6d880x6024ea0 (simPts_task): rmemPartAlloc: block too big e1576 bytes (t0x10 aligned) in partition u0x30f6d88r0x6024ea0 (simPts_taskn): memPartAlloc: block too big 2048c bytes (0x10 aligned) in partition o0xd30f6d880x6024ea0 (esimPts_task): memPartAlloc: block too big 1576 bytes (0x101 aligned) in partition 0x30f6d88(simPts_task):2048 bytes (: block too big   I can add configuration file if it helps...
