Memory usage pattern in openssl - limiting number connections in connections pool

my investigation.. it seems like this is not a memory leak as such but the way openssl allocates memory.. for each connection it looks like once the memory assigned ( like storage certificate ) is not freed.. I am not sure how this works if you point me to some document explaining memory usage within open

BIO in memory usage....

I`d like to understand how a memory bio can be reseted with the internal read counter back to zero for further reusage. e.g. I want to try to read first der and then pem d2i_X509 and then:

Re: [openssl-users] Reg : Openssl peak memory usage

he trusted CA certificates in a single file requires them all to be loaded into memory. When using the openssl command line tool, the amount of memory used depends heavily on the command and data specified. In the end, there is no substitute for measuring the actual process memory usage during

Memory usage on openssl-0.9.8a/

Team, We used "openssl-0.9.8a" version of openssl for the SSL communication, for our desktop based TCP application. When we enable it, looks like the memory growth was alarming around 30 times than normal which is really huge. Can someone throw lights on this version or any known memory leaks he

CRL memory usage

Hi, I want to know the memory usage of CRL file prior to loading ? Basically after call to function "d2i_X509_CRL_bio" to load large CRL file, my free memory goes down drastically. I understand this behavior because openssl allocate the memory to load CRL. I want to understan

retrieve memory usage per session in jsp

Hi Martin, I have this app running on tomcat + oc4j. The app is designed using simple j2ee and struts framework. I would like to watch/monitor how much memory is used per session at any given point of time. Basically i want to design a jsp just to monitor memory usage per session. If

Memory usage

I have an application using openSSL version 0.9.7d. I am able to create 20,000 TLS connections, but my heap size is at 1.5GB. It looks like it is the SSL context. Is there anyway to reduce the memory fotprint? Please CC me directly on any responses

RE: SSL per session memory usage

Martin,   Just one caution with changing the buffer sizes. During handshake, if the SSL engine gets a certificate chain, you should have space to handle it! If you do the changes I have done you may not even have to worry about changing the buffer sizes.   I use memory BIOS, and the way you free th
