Hi, I found two core dumps generated in multi-thread scenarios in ESX part. Case1: libcurl support multi-thread core dump: #12 0x00002aaabea89712 in addbyter () from /usr/local/lib/libcurl.so.4 #13 0x00002aaabea89b86 in dprintf_formatf () from /usr/local/lib/libcurl.so.4 #14 0x00002aaabea8b055 in curl_mvsnprintf () from /usr/local/lib/libcurl.so.4 #15 0x00002aaabea7678f in Curl_failf () from /usr/local/lib/libcurl.so.4 #16 0x00002aaabea6d871 in Curl_resolv_timeout () from /usr/local/lib/libcurl.so.4 #17 0x00000006e8a8f230 in ?? () Fix code: esxVI_CURL_Connect() in esx_vi.c: I add a new line as following: curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1); Case2: libssl support multi-thread core dump: #0 0x0000003f9b030265 in raise () from /lib64/libc.so.6 #1 0x0000003f9b031d10 in abort () from /lib64/libc.so.6 #2 0x0000003f9b06a84b in __libc_message () from /lib64/libc.so.6 #3 0x0000003f9b072fae in _int_malloc () from /lib64/libc.so.6 #4 0x0000003f9b074cde in malloc () from /lib64/libc.so.6 #5 0x0000003f9b07963b in strerror () from /lib64/libc.so.6 #6 0x0000003fa188032a in ERR_load_ERR_strings () from /lib64/libcrypto.so.6 #7 0x0000003fa187fde9 in ERR_load_crypto_strings () from /lib64/libcrypto.so.6 #8 0x0000003fa48309d9 in SSL_load_error_strings () from /lib64/libssl.so.6 #9 0x00002aaaba8e612e in Curl_ossl_init () from /opt/CSCOppm-unit/hypervisor/libcurl/lib/libcurl.so.4 #10 0x00002aaaba8ee6c1 in curl_global_init () from /opt/CSCOppm-unit/hypervisor/libcurl/lib/libcurl.so.4 #11 0x00002aaaba8ee6f8 in curl_easy_init () from /opt/CSCOppm-unit/hypervisor/libcurl/lib/libcurl.so.4 #12 0x00002aaaba0d932b in esxVI_RegisterVM_Task (ctx=0x2aaaba0d96d1, _this=0x5cf54b20, path=0x50e921c0 "10.74.125.50", name=0x2aaac0ae6e80 "root", asTemplate=3228119712, pool=0x5cf54b20, host=0x2aaac0693270, output=0x50e921a0) at esx/esx_vi_methods.generated.c:480 Possible Problem: Two callback functions(locking_function and threadid_func) need to be set. http://www.openssl.org/docs/crypto/threads.html#DESCRIPTION Would you help to give some comments about this two core dump?
