Hi all, 


When using dpdk multi process client server example, I create many clients. After the number of clients 1239, I met this error:

EAL: memzone_reserve_aligned_thread_unsafe(): No more room in config

RING: Cannot reserve memory

EAL: Error - exiting with code: 1

  Cause: Cannot create tx ring queue for client 1239

I have 32G huge page memory. Can anyone give some guidance how to increase the memzone memory? Which parameter should I adjust it? \x16º&¢X¯‰êæjÜúÂ)Ýr‰–yÓ\x1aË_5ónù×m5é\x17­º¹ÏjØh–+âz¹š·>°Šw\¢d^qè¯y×ë¢jk£\x1cºÂ)Ýr‰¡¢Ë{ë^9Û~¶­ëÜ¢[_­©ÜyÊ&ëm·×Ž{鼝¥Ù(®\x03è²×âÇ\b­„DŒLø×Q}×À÷íú+uëÝ¥Ù(®\x05žw_\fk-´×­|Û¾uûM´Ð!\x12M\x17œz+Þuúèš	nš‹myׯë\b§uÊ&ºy'£	õÓ^´×Þ[ÊšèÇ.°Šw\¢cè²×âÇ\b­„DŒLøç}ƒ\x17m5\0\x15žw_\fk-´×­|Û­xûM´Ð!\x12LZè˜éb¾'«1«s¢X¯‰êæjÜúÂ)Ýr‰“¡×¯v—d¢¸\x02qÖ¯‰Ùš­ÈZÞ°Šw\¢g!jŒáºX§»^[çzØ›™Ê&Ê槅©åŠébžìbž×¥r‰¡¹¬\x1e‹\x18žŠ{^•Ê&\r«^YçuðƲÛMz×Í»ßO´ÛM\fzË\x1aâ\x1d׎·çÏ<çMzëMu‚+lzw^™¨¥¢X¯‰êæjÜúÂ)Ýr‰—1¨¥z¸"¶Ç§u隊]¼Ò·7"t^¦\“£^:ߎý×ݶãÏ:‚+lzw^™¨¥¢X¯‰êæjÜúÂ)Ýr‰‘y÷«zw\x1e³^:ߎý×ݶãÏ:‚+lzw^™¨¥¢X¯‰êæjÜúÂ)Ýr‰’¹¸Þr×ivG^¼ð\x13\b{÷çþÞj_åŠ{±šf©ŠŠh®Û(žš\ë…ÁyéÓ…êÞuëÝ¥Ù(®\x05Ìj)fju^®È¨ŸmuäúÞqç^Ç¥ŠËKŠËHv–­r\x17¬jw]ŠÇ.²È¨žÆ›¢ëC<2z÷ivJ+€¸¬µIì¹»\x1c®&Þ†Ûiÿ÷ivJ+ƒù¥þŠmŠ‰ìýׯ™¨¥¶‡^¾·ª¹ë-v—d¢¸,¹¸Þr

Usually that error means that you need to increase the following config 
value:
CONFIG_RTE_MAX_MEMZONE
