求助：freeradius连接sybase数据库出现问题

sunjim

The context allocation routine failed.

The following problem caused the failure:

Invalid context version.
rlm_sql_sybase(sql_init_socket): Unable to allocate CS context structure (cs_ctx_alloc())
rlm_sql: Failed to connect DB handle #0

小弟连接数据库的时候出现以上的错误信息
环境是redhat7.3,freeradius 0.9.2,sybase 12.5
觉得毛病应该出现在数据库上
请各位大侠伸出援助之手
谢谢
