Suricata

Bug #5418

Updated by Victor Julien over 2 years ago

when there is a lot http flows in suricata, the suricata use    memery of linux from 200MB    to 1.2GB whatched by "top" command of linux,and call HTPMemuseGlobalCounter can see http use about 0.9GB memery. 
 when those http flows above time out ,and    call HTPMemuseGlobalCounter can see http using mem become 0 B, but "top" cimmand still show    suricata use    memery of 1.2GB instead of reduce to 200MB。 
 see the code of HTPFree， if htp_memuse become 0， the HTPFree must has been called the same times。 But why the "top" and "free -m" command show the mem still not be freed to linux (centos 7.5)??? 

 <pre><code class="c"> 
 


 void HTPFree(void *ptr, size_t size) 
 { 
     SCFree(ptr); 

     HTPDecrMemuse((uint64_t)size); 
 } 
 </code></pre>
